Sea Spectral Estimation Using ARMA Models [PDF]

open access: yesSensors, 2021
This paper deals with the spectral estimation of sea wave elevation time series by means of ARMA models. To start, the procedure to estimate the ARMA coefficients, based on the use of the Prony’s method applied to the auto-covariance series, is presented.

Regime-Switching Discrete ARMA Models for Categorical Time Series [PDF]

open access: yesEntropy, 2020
For the modeling of categorical time series, both nominal or ordinal time series, an extension of the basic discrete autoregressive moving-average (ARMA) models is proposed.

Revisiting inference for ARMA models: Improved fits and superior confidence intervals. [PDF]

open access: yesPLoS ONE
Autoregressive moving average (ARMA) models are widely used for analyzing time series data. However, standard likelihood-based inference methodology for ARMA models has avoidable limitations.
